TYPES OF SPIN TOPS

There are many types of tops but the following information is about string-wound acrobatic spin tops.  These come in different sizes and materials of course, but the main big difference these days is at the tip; fixed tip, bearing tip, or one-way bearing tip.  

Fixed tip tops were the only kind around up until around the turn of the millennium when Spintastics, Yo-Yo Jam and Duncan came out with bearing tip tops.  Fixed tip just means the tip spins with the rest of the top.  Bearing tips spin independently of the rest of the top.  Here is a chart to compare the two.  We'll talk about one-way bearing tips later.
